>&#13;    Over time it is possible for the Bugzilla database to become corrupt
    or to have anomalies.
    This could happen through normal usage of Bugzilla, manual database
    administration outside of the Bugzilla user interface, or from some
    other unexpected event. Bugzilla includes a "Sanity Check" script that
    can perform several basic database checks, and repair certain problems or
    inconsistencies. 
    </P
><P
>&#13;    To run the "Sanity Check" script, log in as an Administrator and click the
    "Sanity Check" link in the admin page. Any problems that are found will be
    displayed in red letters. If the script is capable of fixing a problem,
    it will present a link to initiate the fix. If the script can not
    fix the problem it will require manual database administration or recovery.
    </P
><P
>&#13;    The "Sanity Check" script can also be run from the command line via the perl
    script <TT
CLASS="filename"
>sanitycheck.pl</TT
>. The script can also be run as
    a <B
CLASS="command"
>cron</B
> job. Results will be delivered by email.
    </P
><P
>&#13;    The "Sanity Check" script should be run on a regular basis as a matter of
    best practice.
